Statement I: A concave mirror is preferred to a plane mirror for shaving.
A concave mirror is a mirror with a reflecting surface that curves inward, creating a hollow shape. On the other hand, a plane mirror is a flat mirror with a reflecting surface that does not curve.
Shaving requires a clear and magnified reflection of the face in order to achieve precision. Let's analyze why a concave mirror is preferred over a plane mirror for this purpose.
Advantages of a concave mirror for shaving:
1. Enlarged and erect image: A concave mirror produces an enlarged and erect virtual image. This means that the image appears larger than the actual object and is oriented in the same direction. This is beneficial for shaving as it allows for a more detailed view of the face and ensures accurate grooming.
2. Converging nature: A concave mirror converges the incident light rays, bringing them together at a focal point. This convergence of light rays helps in creating a clear and focused image. In a plane mirror, the reflected rays are parallel to each other, resulting in a less focused image.
3. Wide field of view: The concave shape of the mirror allows for a wider field of view compared to a plane mirror. This means that more of the face can be seen at once, making it easier to shave different areas without constantly adjusting the mirror.
4. Adjustable distance: By adjusting the distance between the face and the concave mirror, the size of the image can be controlled. This flexibility is not available with a plane mirror, where the size of the image remains constant regardless of the distance.
Statement II: When a man keeps his face between pole and focus of a mirror, an erect and magnified virtual image is formed.
In a concave mirror, there are two important points - the pole (P) and the focus (F). The pole is the central point on the mirror's surface, while the focus is the point where parallel rays of light converge after reflection.
When a man positions his face between the pole and focus of a concave mirror, the following observations can be made:
1. Erect image: The image formed in a concave mirror is always erect when the object is placed between the pole and the focus. This is because the rays of light from the object converge and the reflected rays intersect in front of the mirror, resulting in an erect image.
2. Magnified image: The image formed in a concave mirror is magnified when the object is placed between the pole and the focus. This is because the rays of light converge and the image is formed at a position beyond the focus. The size of the image depends on the distance between the object and the mirror, with closer distances resulting in larger magnification.
Explanation of the statements:
Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I. A concave mirror is preferred for shaving because it produces an enlarged and erect virtual image, which provides a clear and detailed reflection of the face. When the face is positioned between the pole and focus of a concave mirror, an erect and magnified virtual image is formed, fulfilling the requirements for shaving. Therefore, the magnifying and erect
